ALCOHOL-LAMP.

Specification of Letters Patent.

Application filed December 18, 1908.

Patented June 15, 1909.

Serial No. 468,120.

T 0 all whom "it may concern:

Be it known that I, A THUR 0. Fox, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Alcohol-Lamps, ofwhich the following is a specification.

My invention relates particularly to burners for lamps such for instanceas are used by jewelers and other artisans at the workbench. The use ishowever unimportant and while I particularly intend the burner foralcohol lamps, other fluids may be burned in it. The workman isrepeatedly obliged to alter the size of flame. Some burners can beadjusted more or less by raising or lowering the wick. Other burnerspermit the orifice above the wick to be altered. It has been my desireto provide a simple and cheap construction adapted to a wide variety ofconditions. A large or small flame is obtained by appro priate wicks.These wicks can be adjusted in the usual manner if desired. Both wickscan be burned simultaneously or separately and one can be lighted fromthe other.

The accompanying single sheet of drawings illustrates the simplest formof the invention.

Figure 1, is a vertical sectional view of a lamp with a burner embodyingmy inven tion. Fig. 2, is a side view of the main wick tube and wick.Fig. 8, is a side view of a secondary wick tube with the auxiliary wick.Fig. 4, is a side view of the cap for the secondary wick tube.

The font 1, is of any suitable material-for instance-glass of any shapeor design. A ring or collar 2 is secured to the mouth of the font andinternally threaded to receive the lower screw threaded end of the mainwick tube 3. The main wick 4 extends down into the font for absorbingthe fluid such as al cohol in the usual manner. The upper end is allowedto project above the upper end of the wick tube, more or less, dependingupon the necessity of the work in hand. By picking the wick up or down aconsiderable varia tion in the size of flame may be had.

The tube 5 fits outside the main wick tube 3, and has a smaller tubularportion 6 at the upper end. This constitutes the secondary or auxiliarywick tube having the small wick 7 the lower portion of which is coiledor wadded in the upper end of the tube 5 and which projects above theupper end of tube 6 more or less.

Preferably a spring sleeve 8, is interposed between the main wick tube 3and the tube 5 to hold the latter on frictionally.

The small cap. 9, is split up the side so as to allow the sides to yieldand frictionally engage with the outer wall of tube 6. When the cap 9 isremoved and the tube 5 is pressed down, the small wick 7 engages thelarge wick 4 and absorbs the alcohol or other fluid. The small wick canthen be lighted and the size of flame varied by picking the wick up ordown as is customary with ordinary wicks. If 'a larger flame is desired,the tube 5 is removed and the main wick 4 can be lighted either directlyfrom the flame from the auxiliary wick 7 or from any other source.Similarly the small wick may be lighted directly from the flame from thelarge wick when desired.

The small wick will hold suflicient fluid to burn for considerable timeeven when removed from the large wick. Both wicks can therefore be usedat the same time which is often a great convenience. The small flame canbe readily put out by putting on the cap 9. Similarly the large flamecan be snuffed by the tube 5 either with or without cap 9. The workmancan quickly change from the small to the large flame or vice versa as hedesires or using both or extinguishing the one not required.

What I claim is:

1. A lamp comprising a font, a main tube,

a wick therein extending into the font and protruding above the tube forignition, a secondary tube fitting outside the main tube, an auxiliarywick in the secondary tube engaging the main wick and ignitible abovethe secondary tube and a cap therefor.

2. A lamp burner comprising, a main tube, a wick therein, a secondarytube removably fitting the main tube and having a smaller outlet, asmall wick in said secondary tube having a portion in the upper end ofthe tube below the outlet for contacting with the upper end of the mainwick, the main wick being flame productive when the secondary tube isremoved.

3. A lamp burner attachment comprising, a tube having a small neck atthe upper end, a wick extending in said neck and having its lower endwadded or coiled and exposed below in the upper end of said tube wherebyfluid Will be absorbed by said Wick when the tube is placed on a burnertube With eX osed wick and may be ignited above the nec 4. An alcohollamp burner comprising a main burner tube, a main Wick protrudingtherefrom, a secondary tube removably carried by the main burner tube,an auxiliary the secondary tube is removed.
